RTTM Pipeline Leak Detection System

Atmos Tightness Monitor is a statistical tightness monitoring system used to test for leaks in airport hydrants. It uses sequential probability ratio test (SPRT) to detect changes in the overall pressure. SPRT analyzes the pressure variation over a high pressure and then a lower pressure to confirm the tightness of a test section. The system does not require temperature sensors for leak confirmation. Atmos Tightness Monitor leak detection technology is widely used in liquid pipelines, monitoring approximately 200 pipelines many of which transport jet fuel over distances from as small as 100 meters to a few kilometres. Atmos successfully adapted and tested Atmos Tightness Monitor for airport aviation fuel hydrant systems, initially for military airports and naval bases where it has been in use since 2004. Atmos Portable Tightness Monitor was developed based on many years of experience working with leak detection systems on airport hydrants. Testing takes no more than 45 minutes with on-screen prompts notifying the stages of the test to the operator.
